Hello Stuart, Although there is a utility to build HTML image maps, I'm not sure it's made available in source code. In any case, it's not a difficult thing to do from scratch and since it uses many elements from MB programming (file output, map windows, object processing and a bit of arithmetic), it's a good exercise.
The key to image maps is identifying the pixel location of a feature on your map (say a place name). For non-exotic projections, you can do this by simply interpolating x/y given the coordinate min/max of your mapper window and the location within the window that you want to use. Once this conversion is working, you can build hot spots that are simply small circle (for point objects) or more complicated regions. Note with the latter that if your region data is quite detailed, it's worth stripping out redundant (duplicate) points out of the image map. As well as hot spots, you can also use JavaScript tricks to do pop-up information. I use a slightly modified version of Overlib to do the Map Gallery area on the Europa Technologies web site. Hover over the place dots for information. Unfortunately I have only managed to get this working with IE at the moment. http://www.europa-tech.com/gallery.htm It's quote rewarding to get a semi-interactive map working outside of MapInfo, so do give it a try.

I have MIPro 7.8 but only MapBasic 7.0, so I do not have this code .. which I believe was provided from MB v7.5 onwards Thank you in advance Stuart ps. sorry for the re-post --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 15394 --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 15396
